REVERSIBLE HANDLE-MOUNTING FOR BRUSHES.

SPECIFICATION forming part Of Letters Patent No. 624,708, dated May 9,1899.

Application filed February 2, 1899. SerialNo. 704,276. (No model.)

To ctlZ whom, it may concern:

Be itknown that I, HERMANN TRIEST, of the city, county, and State of NewYork, have invented certain new and useful Improvements in ReversibleHandle-Mountings for Brooms,

Similarletters of reference indicate corresponding parts in all views ofthe drawings.

My invention relates to street-cleaning appliances; and it consists ofthe hereinafterdescribed reversible handle-mounting for brooms forstreet-sweeping and for similar utensils.

In sweeping the streets the brooms are used always in one direction onlyand their bri tles are used upon the side-namely, opposite to thehandle-while they remain in good serviceable condition on the otherside.

The object of my invention is to provide a cheap and serviceablemounting for handles of brooms and facilitating the reversing of thehandle without detaching the base-plate from the back of the broom.

The mounting consists of baseplate A, (illustrated in Fig. 1,) providedwith bores e for affixing it to the back D of the broom by means ofscrews 6, handle attachment B, (shown in Fig. 2,) and bolt 0 (shown inFig. 3) for securing the two other parts together.

The base-plate A is provided with a screwt-hreaded bore 0 in its centerand with raised portions a, having their edges cl parallel to each otherand equidistant from bore 0. The recess between these raised portions ais fitted to receive the tongue I) of the handle attachment, having abore a in corresponding position to the bore 0 of the base-plate andsufficiently large to receive the shank of the bolt 0. The thread of thescrew-bolt corresponds with that of the bore 0, and by screwing bolt 0into the base-plate the flange of the screw-bolt is pressed upon thetongue I) of the handle attachment and holds it between the raisedportions CL and locks the parts firmly together.

It will be observed that bolts 0 and F are shown to have caps g on theends of their shanks. ing the ends of the bolts after they are screwedin the base-plate to prevent removing of the bolts from the base-plate.

By unscrewing bolt 0 tongue I) is sufficiently loosened to be raisedabove the level of the raised portions a of the base-plate, and then thehandle may be reversed by turning the handle attachment B on bolt 0 andset in opposite direction. Then the parts of the mounting are againfastened together by screwing bolt 0 into plate A. The changing of thebroom-handle from one side to the other is thus readily and easilyaccomplished by merely unscrewing the bolt 0, then switching the handleto the other side, setting tongue I) in place, and screwing down thebolt. The handle is then as firmly and securely affixed to the broom andin proper posit-ion as when it was originally mounted thereon.

' In the modifiedconstruction illustrated in Figs. 5, 6, and 7 awedge-bolt F is used in place of the screw-bolt O. Wedge-bolt F consists of a screw-threaded shank j and an ovalshaped wedge 7o, situatedbelow the flange f and integral therewith. Tongue b of the handleattachment Bis provided with an oval aperture 0 corresponding in shapeto the wedge 70 and slightly larger to permit 'the tongue I) to belifted closely to the flange f when the wedge-bolt F is turned and thewedge It brought in line with aperture 0 c of the tongue. When tongue 12is thus lifted from the recess between the raised portions a of thebase-plate, the handle can be turned around or reversed in the samemanner as explained above with reference to the other construction, andwhen tongue I) of the ban dle attachment B is again put in place betweenthe raised portions Ct of the base-plate and wedge-bolt F is turned fromleft to right wedge 7.. is brought across aperture 0 c, whereby thehandle is secured firmly to the broom. The tongue Z) of the modifiedconstruction of my improved handle-mounting is flat and These caps v aremade by hammer even, the same as that of the construction shown in Figs.1 to 4; but owing to the shank j being screw-threaded the wedge 70 ispressed upon it in the same manner as if the surface of the tongue I) bean inclined plane. The advantage of this modified construction is thatit doesnot require more than a quarter of a turn of the bolt F torelease and fasten the handle attachment to the back of the broom,whereas in the previously-described construction the screw-bolt 0 mustbe turned several times around to permit reversing of the handle. Bothconstructions, however, are well adapted for the attainment of theobject of this invention. They can be cheaply prod need, are of greatpractical use, and easily applicable to the broom.

Iclaim as myinvention and desire to secure by Letters Patent 1. Areversible mounting for handles of brooms and similar utensilscomprising a base-plate adapted to be secured to the back of the broom,a screw-threaded bore in center of the base-plate and raised portions,having parallel edges, situated equidistantly from and on both sides ofthe screw-threaded bore, a handle attachment having a tongue fittedbetween the edges of the raised portions of the base-plate and providedwith a bore corallel edges, set equidistantly from and on both sides ofthe screw-threaded bore; a handle attachment, having a tongue fitted inthe re cess between the raised portions'of the baseplate and an ovalaperture in position 00116 sponding with the bore of the base-plate, anda wedge-bolt, consisting of a screw-threaded shank, an oval-shapedwedge, fitted into the aperture of the tongue, and a handle, the Wedgeand the handle being integral with the shank of the bolt.

In witness that I claim the improvements described in the foregoingspecification Ihave signed my name in the presence of two subscribingwitnesses.

I-IERMANN TRIEST.
